SPECIAL FEATURES OF THE INTERNAL STRUCTURE OF GLOBULAR GRAPHITE IN HIGH-STRENGTH CAST IRON

摘要

Metallographic and microscopic x-ray spectrum analyses are used to study the special features of microstmcture of pearlite-ferrite high-strength cast iron with globular graphite. It is shown that globular graphite has a polycrystalline structure and bears ferrite over boundaries of pyramidal crystals.
